SAFETY-DEPOSIT CONSTRUCTION.

Application filed August 8, 1919.

T 0 all whom it may concern:

Be it known that we, Josnrrr FREYBERG and LEO F. VVUBBOLDING, citizens,respectively of Austria and of the United States, and residents ofNewport in the county of Campbell and State of Kentucky, have in ventedcertain new and useful Improvements in Safety-Deposit Construction, ofwhich the following is a specification.

Our invention relates to metal safes and the like; and its object is tosimplify the construction of such devices and make them more secure andsubstantial.

ing another part of the shelf or horizontal partition with the jamb slotfor receiving the jamb of Fig. 13 and with the hinge extension thereon;and Fig. 15 shows a modified shelf.

As we prefer to construct these safetydeposit cabinets they are made inunits one of which is represented complete in Figs. 1 and 2; such unitsbeing uniform in height, width and depth so that a number of them may bestacked together and constitute safety-deposit equipment of varioussizes and capacities. Also different units are made with different sizeddeposit. boxes or the same unit may have two or more sizes of boxes init. For instance in the example shown, the lower rows of boxes arelarger than the ones of the upper rows. The principles of constructionremain the same whatever the size.

The construction comprises a case made up of the bottom 1; top 2, sides3 and back 4 preferably of rather heavy flat metal plates arranged in afamiliar way to make the case rectangular; the edge parts of the platesmeeting at the corners of the case and being securely held togetherpreferably by welding.

Inside this case are the horizontal partitions or shelves 5 extendingfrom the open front of the case to the back 4t and from one side 8 tothe other and having their edges firmly secured to the side and backplates throughout preferably by tenoning and welding as at 6 in Fig. 3.The vertical spacing of these horizontal partitions or shelves 5 dependsupon the height which a row of boxes or compartments is to have. Theupright partitions 7 are of the height of the space between two adjacentshelves with their upper and lower edges abutting the shelves and theirrear edges suitably secured to the back 4.; preferably by welding.

These vertical partitions 7 do not extend entirely to the front of theunit. Their front ends are received by jambs 8 or 8' each of which runsentirely from the top to the bottom of the tier of boxes to which itbelongs; the shelves or horizontal partitions 5 being slotted near theirfront edges for these jambs S or 8' to extend through them. The upperand lower ends of the jambs fit snugly against the top 2 and bottom 1 orwhere a wider box is encountered above or below against the adjacentshelves or transverse partitions 5. Thus each box or comverticalpartitions 7, which members, passpartment is completely closed and madedistinct from all the others at its top, bottom,

sides and back.

Preferably the jambs 8 and 8 have members flanking the front edge partsof the i the front ends of the compartments. Eac

door 9 is a heavy metal plate of rectangular shape fitting snugly in theopen front of the box or compartment whatever the size of that may be.The upper and lower edges of the door 9 are substantially horizontal andthe front or free edge 10 is somewhat beveled inwardly to pass the jamb.The rear or hinged edge has the tongue 11 running from top tobottom ofthe door adjacent to the inner or rear surface of the door. The jamb 8is provided with a vertical groove into which the tongue 11 enters whenthe door is closed. The formation and arran e ment of these grooves willpresently be cescribed. A look 12 is mounted on the inside of each doorand, as here shown, is provided with two cylinders 13 extending throughthe door for operation of the locks by means of two keys. The bolt 14:of the look engages with a suitable strike as will more fully bedescribed later. When the door is closed and locked its front end isheld by the lock and its hinged end is held by the tongue 11 in thegroove of the j amb. The security of closure of the door is thereforenot dependent upon the hinges; and these latter may be madeonlysubstantial enough to support the door for swinging and to withstandthe wear and tear of ordinary use of any hinge.

The hinges to accompany this interlocking tongue 11 extend out from theface of the door and over in front of the jamb where they have theirupright pivot pins. The shelves or horizontal partitions 5 have hingeextension 15 immediately in front of the respective jamb slots withopenings 16, and the. hinge pins, fastened in the hinges,

extend down into these openings. There are similar extensions 15 on thetop 2 and bottom 1.

As shown herein hinges are preferably of the kind disclosed and claimedin our copending application Serial No. 318,229, filed August 18, 1919,as will presently be dethat other arrangements may be made; all of thedoors swinging the same way if there is no need for any of them swingingotherwise. But where this is provided for there is some difference bothin the j ambs and in the hinges because this involves the bringin r ofthe hinged ends of right-hand and left-hand doors adjacent.

lVhere the hinged end of one'door is ad j acent to the locking end ofthe next door, as at the left in Figs. 3 and 1, the jamb 8 is made witha shoulder 17 behind which the tongue 11 enters, and the other side of jamb 8 has the strike 18 against which the free end of the other doorabuts and behind which engages the bolt 14 of the lock of that door.Where the hinged ends of two doors are adjacent as at the right in Figs.3 and 4:, the jamb 8 has the grooves 17' on opposite sides to receivethe tongues 11 of the two doors. For these left-hand-swinging doors astrike is provided by means of a strip 18 against the adjacent side 3 ofthe case which strip 18 extends continuously from top to bottom throughrecesses in the transverse partitions or shelves and by means of whichdisplacement of the strip 18 is effectively prevented.

e prefer to form these jambs-S and 8 of sheet metal; a long strip of therequired width being folded on itself to form the two side members 19 ofthe jamb 8, or 19 of the j amb 8, and the junction of the two foldsconstituting the front face 20 of the jamb in each instance. The twofolds are separated adjacent to this junction to give the jamb greaterwidth and so that one fold having a compound bend inthe j amb 8 willform the shoulder 17 and thereby lie against the other fold; while thisother fold has, back a sulficient distance, four successive bends eachat right angles to the last so that the strike 18'is of substantiallyrectangular cross-section and hollow and the last bend is made so thatthe member 19 on this side is spaced from the other member 19 justenough to receive the front edge part of the vertical partition 7 asbefore mentioned. F or this jamb 8 the slot 21in the horizontalpartition or shelf .5 'has the front wider part 22 with its front endsubstan-.

tially even with the main front edge of the shelf 5 and within thelimits of the hinge extension 15. The rear end of this wider part 22forms the shoulder 23 that comes behind the shoulder 17 of the jamb 8;and at the other side the slot 21 has the recess 2 1 that receives thestrike 18 of the jamb while the rear main part 21 receives the members19 and holds them against the opposite sides of the vertical partition7. V

The other kind of jamb 8 merely differs in its shape whereby the grooves17' are formed at opposite sides and between which the two folds ofsheet metal lie together and again separate rearwardly to form themembers 19 with the end of the partition 7 between them. The jamb slot21' in the shelf 5 comprises the front part 22 and the narrower partjoining it to the rear part so that lugs 23' are left projecting towardeach other into the grooves 17 of the jamb. This slot 21 lies wellwithin the limits of the respective hinge extension 15 and with itsfront end substantially even with the front edge of the shelf 5.

lVhere the hinged end of one door is adjacent to the free end of thenext door the hinge 25 is of full depth where it receives its pivot pin;but where hinged ends of doors are adjacent, the hinges 25 are made withthese pivot-pin-receiving parts only half the height of the hinge andthe meeting hinges are inversely arranged so that the two half parts arein vertical alinement with the pin through them. In this case the pin isfastened in one and left loose in the other hinge 25'.

According to our invention in the aforementioned copending applicationthe upper and lower edges of the door 9 near its rear or hinged end haveslots 26 cut in them extending diagonally in from the front of the doorto cylindrical sockets 27 wider than the slots. The hinge 25 or 25 ismade with its middle part or shank 28 just wide enough to fit tightly inthe slot 26 and having on its end the cylindrical part or head 29 thatfits tightly in the socket 27. The slot 26 and socket 27 are of just theright depth that when the hinge 25 or 25 is driven into them the upperor lower edge of the hinge will come flush with the top or bottom edgeof the door, as the case may be. The pivot-pinreceiving part 30' of thehinge 25 of the full height of the hinge, or the part 30 or the hinge 25of half the height is of substan tially the same diameter as thecylindrical head 29; but preferably while the shank 28 meets the head 29radially so as to leave vertical shoulders at each side, it meets thepart 30 or 30 at a tangent. This formation vith the proper arrangementresults in throwing the shank 28 of the hinge away from the jamb 8 or Sto afford ample clearance when the door closes. It will be understoodthat these hinges are thus set in the doors at the right angle to bringtheir pivot receiving parts 30 or 30 in vertical alinement with pivotopenings 16 in the hinge extensions 15 when the doors are closed. Thesehinges are driven into the door slots and sockets under very heavypressure so that they are as substantial as if formed in tegral with thedoor.

The shelves or transverse partitions 5 and top 2 and bottom 1 may havetheir front edge parts 15' straight throughout and extended as farforwardly as the hinge extension 15, as shown in Fig. 15, afiordingeveneach other into these grooves.

more protection against cutting away to remove the jambs.

The hinges described are preferred for reasons given in the co-pendingapplication; but it will be understood that any hinge properlyproportioned and arranged on the fronts of'the doors to cause them toswing properly will answer to the purposes of the present inventionwhich having had its construction fully described, may now be describedwith relation to its uses and advantages.

The transverse partitions or shelves 5 being welded or otherwise firmlysecured in the case and the jambs 8 or 8 being continuous from top tobottom through the slots 21 or 21 of these partitions or shelves 5 thelatter efiectively prevent forward displacement of the jambs. Theupright partitions 7 being engaged and having their front ends enclosedby the flanking members 19 or 19' of the jambs, cannot be displacedforwardly nor sidewise. The members 19 or 19 in this function ofsecuring the upright partitions 7 are reinforced by running through theslots 21 or 21, the opposite edges of which closely flank these membersand hold them toward each other against the end parts of the partitions7.

The transverse partitions or shelves 5 having the extensions 15 or 15'in front of the respective slots for a considerable distance past theface of the respective jambs at both sides would, even without any otherinside engaging means, necessitate the cutting away of the entire hingeextension to open the slot forwardly for forward withdrawal of the jamb.And With either the jamb 8 or 8 there areadditional engaging meansfurther inwardly, i. e., in the jamb 8 the recess 2 1 with theprojection or strike 18 engaging therein, and with the jamb S theopposite grooves 17 with the lugs 23 of the recess projecting towardThus, even without the hinge extensions, or if these should be cut away,it would still be necessary to out far within the transverse partitionor shelf 5 to remove the metal lying in front of these inside engagingmeans. Up or down withdrawal of the jamb is effectively prevented by thetop 2 and bottom 1 of the case, which when installed are reinferred bthe foundation or other units under the bottom and other units or wallover the top. It will be seen therefore, that the case and its containedtransverse and upright partitions and its jainbs are all securely boundtogether; those parts not welded together being engaged with each otherin such a way that none of them can be disengaged without cutting awaythe metal for a considerable distance. Not only is unauthorized accessfrom the outside prevented in this way but access from one compartmentto the other is effectively prevented because the transverse partitionsor shelves are continuous throughout the unit from side to side and fromfront to rear and welded or otherwise effectively secured to the sidesand back and the upright partitions 7 are firmly secured to the back 4as hereinbefore described, and their front ends aresecured by extensionfar in between the flanking members 19 or 19' of the jambs. Theseengagements between the transverse partitions and the jambs and betweenthe latter and the upright partitions, locking them as they do withoutthe necessity of welding in these parts, permits a considerable savingin the construction. This also applies to the mounting of the strip 18against the right side 3 which is held merely by passing through therecesses in the transverse partitions or shelves 5 and those need not bewelded to the adjacent side.

Having the jambs 8 and 8 firmly secured against removal, the locking ofthe doors, in such a way that they cannot be opened by removal of thehinges when locked, is very effectively provided against by the swingingof the tongues 11 behind the shoulder 17 or 17 of the jambs; and thissecurity of the jambs of course also lends itself to the locks ofthedoors with their bolts 14 engaging behind the strikes 18 of the jambs,or, in the case of the lefthand-swinging door, of the strip '18,provides security of these doors in this respect.
